Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications, see the Electrical Characteristics tables.
Note 2:
When the output of the V
COM
buffer exceeds the supply rails, while sinking or sourcing 100 mA, the V
COM
output is susceptible to latch.
Note 3:
Human body model, 1.5 k
in series with 100 pF. Machine model, 0
in series with 200 pF
Note 4:
The maximum power dissipation is a function of T
J(MAX)
,
θ
JA
and T
A
. The maximum allowable power dissipation at any ambient temperature
is P
D
= (T
J(MAX)
– T

)/

JA
. All numbers apply for packages soldered directly onto a PC board.
Note 5:
Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing condition result in very limited self-heating of
the device such that T
J
= T
A
. No guarantee of parametric performance is indicated in the electrical table under conditions of internal self-heating where T
J
>
T
A
.
